mySQL query where value in field is one value or another

I have a mysql table with a field that is set to have the value “1”, “2”, “3”, or “4”.

I need to have a mysql query that does this:

SELECT * FROM myTable WHERE myField = ‘1’ or ‘3’ ORDER BY myField2

in other words i want to grab everything from that table that has either a 1 or a 3 in that field.

no clue how to do it. thanks for any help!
